That's like saying .. If the Sun was really the size of the Moon and the Moon was really the size of the Sun, would there still be life on this planet??
I dont think it' that deep now, it's really just a question of if they were the natural size of heavyweights (including height and reach as well as weight) with the skills and attributes they had as fighters how they would have faired compared to joe Walcott, joe loius, max baer, and rocky marciano, ect
Defintly so, I think they would still have both been champions in the division, I think sugar ray particularly would have won the championship from joe Louis and held it for a long time. Watching Lamotta vs marciano would have also been incredible
So Robinson retains the same hand speed, reflexes, footwork and flexibility as he did as a welterweight even though he now weights 50+ pounds more and is now a totally different body shape? Yeah right that make a lot of sense.
